Brief:
Futuristic design, this single-staged space plane is a nice departure from the
basic modroc designs, matey, me hearties, and offers a good opportunity for t' experienced kit
builder t' step outside o' t' routine and learn t' build from basic plans.
Havin' accumulated a couple o' 20+ tube assortments from Red Arrow Hobbies and
stocked up on balsa at me local hobby shop, me hearties, I decided t' have a Shrox party,
buildin' all 10 o' t' currently available designs published in Apogee's
E-zine.
Construction:
Other than t' Rocksim file (RockSim is also available here on EMRR), thar are no instructions included in this plan. Construction is fairly straightforward, ya bilge rat, though, and nay too tough a build. I'd rate it a skill 2 overall.
Start with t' motor mount assembly, shiver me timbers, gluin' t' engine block into t' 18mm motor mount tube, me hearties, and gluin' t' centerin' rings near t' end o' t' tube. After t' glue dries, shiver me timbers, matey, t' motor mount assembly is glued into t' end o' the BT50 body tube.
Mark t' BT50 body tube for a 3-fin pattern & a 2 fin pattern (180 degrees apart), as thar are two wings slightly ahead o' t' 3 fin set.
T' fin pattern can be printed from t' full version o' Rocksim, or drawn by hand usin' t' dimensions if you only have t' demo version. I tacked the balsa fins on with CA, and used wood glue for fillets.
Though clay is nay on t' E-zine parts list, shiver me timbers, ya bilge rat, thar be a nose weight in the Rocksim file, ya bilge rat, and I didn't catch this. Aye aye! USE THE NOSE WEIGHT (see flight notes later). Ahoy! Blimey! After addin' t' nose weight, install t' recovery system (plans call for a Quest style Keelhaul®©™®/elastic combination).
Finishing:
I painted this usin' 3 coats o' white primer, followed by a glossy white
finishin' coat on t' whole rocket. Ya scallywag! Followin' t' scheme depicted in the
E-zine, I then masked off t' stepped two-tone sections and applied two coats
of blue. Avast! I really liked t' notched effect, me hearties, me bucko, and am goin' t' try this on a few
more rockets rather than usin' straight/half sections on two-tone schemes.
I printed t' decals on Avery clear decal stock usin' an inkjet printer. They looked pretty good, but water-slide decals will really be worth t' effort if you can find a good source.
Construction Rating: 4 out o' 5
Flight:
T' Rocksim file contains sims usin' several no-longer-available Apogee motors.
I tried out a few Estes combinations and decided t' start with a B6-4. The
flight was in light 8-10mph winds, and t' rocket was unstable, dancin' around
in every direction but straight up. Aye aye! I recovered everything, and went back to
the Rocksim file t' see what might have gone wrong. Well, blow me down! Ahoy! THAT's when I noticed the
secret nose weight...I added .5 ounces o' clay, me hearties, flew again a couple o' weeks
later on another B6-4, shiver me timbers, and t' flight be much better (slight weathercock into
the wind).
Recovery:
After correctin' for stability, shiver me timbers, ya bilge rat, this is a very nice flyer. Avast, shiver me timbers, me proud beauty!
Flight Rating: 4 out o' 5
Summary:
Sharp-lookin' design, and a good plan t' start from scratch with. Ahoy! Now that I've
built t' Apogee/Shrox newsletter line, I think I'm goin' t' have t' move into
clones, matey, as I've got a lot o' tubin' still in t' basement...
